[geos-devel] Gsoc 2013

[vishal tiwari]

Hey!
I have submitted my GSoC Proposal for the project "Adding Voronoi Diagrams
to GEOS" here:
http://www.google-melange.com/gsoc/proposal/review/google/gsoc2013/vishal_tiwari/13001

kindly review it and give me feedback so that i can further improve it
before the application deadline.
Thanks,
Vishal Tiwari
